European Map COVERAGE  DETAIL

Unfortunately,  the amount of detail shown in various European maps varies WIDELY.  Coverage in the UK is excellent and Germany we rate as very good.  However,  other countries have variable amounts of coverage and often do not have street level detail of smaller towns and cities.  Here is Garmin's statement about the level of detail in map coverage:

"Well, first of all, we don't ever have ALL residential streets for any product.   But, it is a little more difficult to describe for the European products.  These are NavTech based maps and they have residential streets in the major cities.  However, <for instance> the Spain product really only has residential street level detail in 4 cities throughout the entire CD. Whereas, the UK product has residential streets almost everywhere. I usually tell people to expect <highly detailed>  coverage of just the major cities and its a bonus if the smaller ones show up too."
